T/SCDA 091-2021 DP Prestressed Concrete Pile
Basic Information
Scope
Main technical content: 1. DP prestressed concrete pipe piles (abbreviated as DP pipe piles) are suitable for low-base foundation projects of industrial and civil buildings and structures with seismic fortification intensity of Grade 7 and Category B, as well as for low-base foundation projects of railways, highways, bridges, ports, water conservancy, and municipal engineering. When the technical conditions are similar, they can also be used for low-base foundation projects. 2. DP pipe piles are suitable for low-base foundation projects that mainly bear vertical compression and tensile loads. When used for foundation projects that bear large horizontal loads, special design and verification calculations should be carried out. 3. When encountering liquefied soil layers, the selection of DP pipe piles should comply with the provisions of the "Technical Code for Building Pile Foundations" JGJ 94. 4. The selection of Type A piles should comply with the requirements of relevant standards and regulations of the city.
